Phylogenetic Analysis of the Mycobacteria and Diagnosis of Paratuberculosis by 16SrRNA Amplification and Probing
Comparative 16S ribosomal RNA sequencing was used to infer natural relationships among selected mycobacteria and related organism, with emphasis on members of the Mycobacterium avium-complex (MAC). All mycobacteria examined formed a closely related (average similarity $>$95%) and exclusive …

Host Specific Microbial Source Tracking and Quantification Using the Partial 16SrRNA Gene Sequence of Bacteroides on the Wilson's Creek Tributary in Southwest Missouri
… PCR assay using Bacteroides host-associated 16SrRNA marker genes was used, along the with Colilert E. coli MPN enumeration method for this survey. There were multiple occasions at each site where the E. coli MPN exceeded the Missouri DNR recommended safety standard of 126MPN/100ml. …

Host Specific Microbial Source Tracking and Quantification Using a Partial 16SrRNA Sequence of Bacteroides on the Finley River, a Tributary of the James River in Southwest Missouri
<p>Microbial source tracking (MST) is a general term given to any process which aims to determine the source of microbial contamination found in an environmental (usually water) sample. These methods include both phenotypic and genotypic strategies. In this study, quantitative PCR was used to …

Microbial degradation of high molecular weight polycyclic aromatic hydrocarbons
… basis of multiple sequence alignment analysis of 16SrRNA gene sequences. Differentiation of the three strains was possible by pulse field gel electrophoresis and DNA:DNA hybridisation methods. The St. maltophilia strains had similar degradative profiles to community five.

Diversity of Free-living Nitrogen Fixing Bacteria in the Badlands of South Dakota
… free medium (NMF) under hypoxic conditions. The 16srRNA and nifH genes were amplified and sequenced. This was complemented using a culture independent approach, amplifying nifH from soil DNA extracts. The 16S rRNA gene data indicated a diversity of putative free-living diazotrophs across 4 phyla …

The development of tools to allow genetic and genomic analysis of Frankia
… gln A, glnII, a truncated hemoglobin, and the 16srRNA. The development of these physical maps of Frankia has provided a stepping-stone to facilitate the sequencing of the entire genome of isolates, EAN1pec and Ccl3.</p><p>Another important step in further understanding the genetics of this …

Molecular characterization of mycoplasmas species isolated from the genital tract of Dorper sheep in South Africa
… and genetic molecular methods. In this study, 16SrRNA gene-based PCR assays and gene sequencing was used for the detection and characterization of Mycoplasma species from cases of ulcerative vulvovaginitis and balanoposthitis in Dorper sheep in South Africa. This investigation was conducted on …

Effect of soil amendments on the chemical transformation of arsenic and the microbial diversity in rice paddy microbiome
… rice grain, the effects were not pronounced. The 16SrRNA and arsM bacterial abundance in rice rhizosphere soil at 14 d, 56 d, grain fill (107-134 d) and dry stage (145-170 d) revealed a significant increase in both arsM and 16S rRNA gene copy number over time. The highest bacterial abundance was …

Taxonomic, systematic, morphological and biological studies on Palaemon Weber, 1795 (Crustacea: Decapoda: Palaemonidae)
… of the subfamily Palaemoninae based on the genes 16SrRNA and Histone (H3), representing the largest dataset to date on this subfamily. As the structure and morphology of an animal may also be heavily influenced by its function, an investigation into the structure of the mandible, a feature that …

Metagenomanalysen von zwei Habitaten mit (hemi-)cellulolytischen mikrobiellen Gemeinschaften
Die Analyse von Metagenomen ermöglicht nicht nur einen Einblick in die mikrobiellen Diversität eines Habitats, sie kann auch durch die Durchmusterung von Umweltgenbanken zu der Entdeckung von neuartigen, biotechnologisch anwendbaren Biokatalysatoren führen. In der vorliegenden Arbeit wurde zum …
